pplicetion filed July 3, 1908. Serial No. 441,738.

` To all -ww'm 'it mayeoncern:

Be it known that l, ALFRED B. DAY, a citizen of the United States, residing etKnoX- ville, in the county of Knox and State of Tennessee, have invented e new and useful Improvement in llt heels; of which the following 1s s. specification, 'reference being had to the accompanying, drawing.

My im rovement relates generally to Wheels, -pu eye, etc., arrenged to rotate upon one end of e. shaft or axle.

'lhe improvement is specially e plicable to mine cars and similar eers in W. ich the axles ere secured to the cer body While the wheels are secured rrotatably around the ends of the axles.

Yllreobject of the invention is (l) to rovide 'enxercient means of holding the W eel on the'ale without drilling'orfgrooving the ready'reinovel 'ofthe wheel from the axle without removin the pedestal or bearing box, (2) to provie for such-removelfoi the Wheel While the Wheel is e single casting without loose ce s. and other parts, (3) -to rovidee Wheel tliet een be adapted to roller eerings and other enti-friction construction and Whieh'will allow e eontinuous beering'surface on the aide oin the end of the latter to the pedestal, and '(4) to provide 'a constrretion requiring minimum. amount of machine Work and which' is et the same time practically dust and oil tight, to the end that oil or similar lubricant maybe oonstently kept Within the hub and dust, oinders,

l ete., excluded therefrom.

tion will be termed the reerH side or por-` tion. f

In' the particular form of the structure shown by the drawings, i is one end of a car axle which is secured to e oer. 'The bearing' surface of this axle is of plein cylindrical form and the entire eXle is preferably of such form, for then no mechinexvork of any kind time providing. for the" is required thereon other than cutting the `end smoothly in a plane to which its exis is perpendicular.

'lhewheeL 2, hes e rim, 3; spokes, Ll, and e. hub, 5. The body ofthe hub is cylindrical end it has en interior Cylindrical chamber extending from the rear to the front end of the hub, the reerJen-d being open to the saine diameter als the interior chamber. Across the front end of seid chamber extends en end Well, 6, which is cast integral with the remainder of the hub'. Through'the center of seid end Well extends an aperture, 7, into which is iittedn screw plug, 8. Said e. erture isdesigned for the introduction oi' lu ricent.` On the inner fece oi seid Well are l three shoulders or ebutments, 9, equi-distant from each other and bearing against the end of the shaft, l.

A sleeve, l0, surrounds thesheft, .-l', from the end ofthe letter to the pleno of thef'end of the hub, seidsleeve preferably fitting said axle loosely enough to turn and permit easy reniovel. Around seid sleeve is a. series of anti-friction rollers, il, as long es the sleeve. Surrounding said rollers is another sleeve, 12, which is of the seme length es seid rollers and the sleeve, .10. Seid sleeves and said rollers beer by their front ends against the nbutme'nts, Q. At its reel', seid hub is exnox, 18,"heving en annular pecking groove, 14, in Which is pecking, l5, for preventing F4'the passage of oi., dust, or Water. The box, 13, is secured to the car body, ,16, inenydesired manner. Said` bon has en .inner dat feo-e, 17, which ormspen abutment lfor the rear end of the hub and the rear ends of the sleeves, 10 end 12, and the enti-friction rollers, ll. lthes already been pointed out that the front ends of the axle and seid sleeves end rollers beer egeinst the abutments, 9, in the iront end of the hub. To r,me-intein this position of these parte, `e hey is seated in the bearing box, i3, and mede to engage the hub within said box. The drawings show seid lrey in the form of a bolt, 18, extending transversely through. the lower portion of seid box approximately tangentielly to e circumferential groove, 19, in the outer face of theliub, Smthet e. portion of seid bolt Will rest in seidv groove.

As will be readily understood from en inspection of the dre-Wings, the huby is free to turn, the rooved portion thereof slip in on seid bo t, but seidbolt prevents the iu l tended e. suitnlle distance -to enter e bearin from Siippiiig end-Wise. it is to be obseived. i .with seid box and teiigentieiiy engaging seid that the eseentief part loi.: said. groove is the i'eei' fece theieof; iol" it is neeeseeiy oniy that the key hold the hub from moving for Werd (toward the right), and foi` this it 'is euioient if'there is en ennuer shoulder such es is presented by the rem' 'Wall or faire of said gi'oove. in Fig. 4 the slope of the iorwei'd poion of the gieove is such :ie to ieftve prac# tic/elly oiiy the one ehouider.

it will be observed het the `-wheel een be f removed from the axle by simpiy removing the key boit, i8, and pulling the Wi'ieei @utf The only meohme Woik needed by the' wheel is the 'finishing oi the iiub ohembei end the threading of the aperture, 7. This oeils .for only easy and simple inthe work.

The bearing box and the key together constitute mechanism abutting agdirist the imiei end of the roller bearing mechanism eed 'the hub and engaging the hub against movement on the-eide away from the Eea-ring box.
